... As heat conduction plays a vital role in affecting the outcome of the nanofluid droplet impacting dynamics, we further demonstrate how the heat transfer rate influences the impacting dynamics of the nanofluid droplet by using numerical simulations. 47,48 We perform numerical simulation of the nanofluid droplet (diameter = 0.5 mm, nanofluid droplet temperature = 25°C) impacting on the cold MN200 and cold N superhydrophobic surfaces (surface temperature = −5°C) at an impacting velocity of 1.4 mm/s by using the Volume-of-Fluid (VOF) method. The temperature distribution of the cold surface upon the nanofluid droplet impact is calculated via the Pressure-Implicit Splitting of Operators (PISO) algorithm. ...

... This is more effective in filtering submicron particles in the air, significantly improving filtration efficiency without increasing air resistance. The findings of many scholars have confirmed this point [26]. However, the electrostatic persistence of electret materials is one of the main factors limiting their performance [27]. ...

... [6][7][8] Designing a self-healing coating capable of autonomously repairing these microscopic cracks holds paramount significance. 9,10 Inspired by biomimicry from nature, researchers have developed a range of self-repairing materials categorized as intrinsic self-repairing materials [11][12][13] and extrinsic selfrepairing materials [14][15][16][17][18] based on the presence of healing agents. In 2001, White et al. 19 described a microcapsule-based self-healing material comprised of dicyclopentadiene (DCPD) microcapsules coated with urea-formaldehyde and a substrate-embedded Grubbs catalyst. ...

... Among many wet chemical methods, solvothermal reflux method, also known as thermal decomposition or one pot method, is widely used for synthesis of metal nanoparticles (Pt, FePt), semiconductor nanoparticles (CdS, CdSe), and insulator nanoparticles (ferrites) and were grown in high boiling point (BP) organic growth solvents in the presence of suitable surfactants and reducing agent [1,12,13]. Solvothermal reflux method produces well crystallined and well dispersed colloidal superparamagnetic nanoparticles (SPNPs) which are suitable for biomedical applications such as drug delivery, diagnosis (MRI), superparamagnetic hyperthermia (SPHT) [14], and ferrofluids for heat transfer [15,16] and water treatment [17,18]. Long chain organic molecules such as oleic acid (OA) and oleylamine (OAm) are majorly used as surfactants in solvothermal reflux method. ...

... It should be noted that the physical units of thermophysical properties must be converted to lattice units during present simulations. The specific conversion method can be found in Ref. 47. ...

... In view of this, the spheropolyhedralbased DEM was used for shape characterization and contact detection, and a modified Johnson-Kendall-Roberts (JKR) adhesion model was proposed to calculate adhesion forces among vertices, edges, and faces of non-spherical particles in our previous work. 31 Building upon this, the present study will utilize this model to investigate the influence of aerosol particle shape on the deposition process during single fiber filtration. ...

... This technique enables the observation of microscopic features during the mobility of atoms as well as the determination of the trajectories of atomic motion. It is an effective additional tool for analyzing the outcomes of the experiment [78][79][80][81]. Due to the high computing time and spatial scale requirements, MDS have now been widely used in MD to research membrane transport and optimize membrane design, albeit primarily for nanostructures without the involvement of phase change. ...

... These methodologies have facilitated the consideration of monodisperse and polydisperse particles with varying particle properties. It has been demonstrated that factors such as high surface energy, 12 high rolling friction, 13 low elastic modulus, and the involvement of mixture deposition processes 14 can significantly enhance filtration efficiency and influence deposition structure. However, the adhesive force interacts with other forces, such as elastic repulsion and sliding resistance, in a complex nonlinear manner that cannot be easily superimposed with other forces. ...

... According to their findings, the maximum obtained freshwater, recovery ratio, and water productivity of the device occurred at a mass flow rate ratio of 3.5. Wu et al. [25] used waste heat from a fishing boat to generate freshwater in a HDH system. Their findings revealed that the HDH unit's highest thermal efficiency and water productivity were 48.16% and 64.5 kg/h, respectively. ...

... An alternative technology that has attracted increasing interest in the past few years is ionic membranes [20][21][22][23][24][25][26][27]. These devices work based on electrolysis, and they typically comprise a proton-conductive electrolytic layer sandwiched between two porous electrodes with catalytic layers composed of noble metal particles. ...
